A properly hot pan and a thin cut of steak means just 2 to 2 and a half minutes per side for medium-rare, with a real crust to show for it.

A chimichurri butter melts straight over the hot, sliced steak instead of sitting on the side, so every bite gets a hit of garlic, parsley and chilli.

Sweet potato mash and a fried egg round it out, a proper steakhouse plate at home in 35 minutes.

Why You'll Love This Steak, Mash and Eggs

A proper steakhouse plate, no reservation required

Bringing the steak to room temperature and patting it fully dry before it hits the pan is what actually gets you a real crust, skip it and you'll cook unevenly from edge to centre.

Resting the steak the full 5 to 10 minutes before slicing keeps the juices in the meat instead of pooling out onto the board.

Chimichurri butter melting over the hot steak does more work than a sauce on the side ever could, garlicky, herby, and right where it needs to be.

Ingredients

Steak

  • 400 g Rump or Scotch (Ribeye) Steak
  • 15 ml Olive Oil
  • Salt & Pepper

Sweet Potato Mash

  • 400 g Sweet Potato
  • 200 g Potatoes All Rounder
  • 80 g Greek yogurt
  • Salt & Pepper

Chimichurri Butter

  • 50 g Unsalted Butter Softened
  • 5 g Flat Leaf Parsley Chopped
  • 1 Garlic Clove
  • 5 ml Red Wine Vinegar
  • 1 g Dried Chilli Flakes
  • Salt & Pepper

Serving & Garnish

  • 2 Whole Eggs
  • Flat Leaf Parsley Chopped

Method

  • Bring the steak to room temperature and pat dry. Rub with olive oil and season with salt.
  • For the chimichurri, mix all ingredients until combined. Chill for 30 minutes โ€” spoon or slice over steak slices.
  • Boil all-arounder potatoes & sweet potatoes in a pot for 22-25 minutes or until fork tender. Drain through a colander.
  • Mash, using a rice or handheld masher. Add in yogurt, salt, and pepper. Serve chunky or smooth.
  • Place a pan over medium heat, add oil and crack in 2 eggs. Cook for 3-4 minutes or until the whites have just set. Remove from the pan.
  • Heat grill pan or heavy skillet to smoking hot. Sear the steaks for 2 to 2 1/2 minutes per side for medium-rare. Rest 5โ€“10 mins โ€” slice thin against the grain.
  • Serve in bowls, garnish with flat leaf parsley and cracked black pepper. Dig in.
Chef's Tips
Bring the steak to room temperature and pat it fully dry before searing, as written โ€” any surface moisture stops a good crust from forming, and starting cold means an uneven cook from edge to centre.
Get the pan properly smoking hot before the steak goes in โ€” that's what gets you a real sear in just 2โ€“3 minutes per side without overcooking a thin cut like this past medium-rare.
Rest the steak the full 5โ€“10 minutes before slicing against the grain, as written โ€” cutting into it early lets the juices run out onto the board instead of staying in the meat.
Storage & Reheating
This one's best eaten fresh, as intended โ€” the fried egg won't reheat well (the yolk overcooks and the white turns rubbery), and the chimichurri butter is meant to melt over hot steak straight off the pan.
If prepping components ahead, the mash and chimichurri butter both keep refrigerated for up to 3 days in separate airtight containers. Reheat the mash gently with a splash of water to loosen it, and let the chimichurri butter come back to room temperature or melt it fresh over freshly seared steak and a fried egg cooked just before serving.

Common Questions
Why bring the steak to room temperature before cooking?โŒ„

A cold steak straight from the fridge cooks unevenly, browning on the outside before the centre catches up. Room temperature gets you a more even cook edge to edge.

Can I make the chimichurri butter ahead of time?โŒ„

Yes, it keeps refrigerated for up to 3 days. Let it come back to room temperature, or melt it fresh straight over the hot steak when you're ready to serve.

Can I cook the steak to a different doneness?โŒ„

Yes, just adjust the time per side and pull the steak at the internal temperature you want: rare 50ยฐC (120ยฐF), medium-rare 55ยฐC (130ยฐF), medium 60ยฐC (140ยฐF), medium-well 65ยฐC (150ยฐF), well done 71ยฐC (160ยฐF). Pull it off the heat about 3-5ยฐC (5-10ยฐF) below your target, since the temperature keeps rising as it rests. A thermometer is worth it on a thin cut like this since time alone is easy to misjudge.

Can I swap the fried egg for something else?โŒ„

A poached egg works just as well if you'd rather. Either way, cook it fresh just before serving, it doesn't hold or reheat well.
